Artifact from myomectomy/C-Section on MRI images – what does this mean for MR-guided focused ultrasound candidacy for uterine fibroids?

International Journal of Hyperthermia, 2019
Background: Magnetic resonance-guided focused ultrasound (MRgFUS) is used for non-surgical treatment of uterine fibroids, often in patients who have had prior myomectomy or Cesarean section. The presence of post-surgical MRI artifacts along the beam path
